You can confirm it for yourself by looking at cockpit photos of F111s (any model, any era) when parked on the ramp. You'll notice that the wing sweep lever is always fully forward (16 deg).
The Hook and park Brake handles were of similar(ish) shape and size and mounted about 10cm apart, just fwd of the wing sweep lever(Park break was grey, hook handle was yellow) . Many a Pig driver blew the hook down while attempting to engage the park brake.
